New Release Candidate

It is well known fact that it takes time to build quality, and sometimes
more time than expected. The OpenWrt developers would like to announce
the availability of OpenWrt Kamikaze 8.09 RC1.
You can find it at http://downloads.openwrt.org/kamikaze/8.09_RC1

Release Candidate 1 for Kamikaze 8.09

New changes/features include:

    * Busybox upgraded to 1.11.2
    * Kernel upgrades for all targets
    * uClibc upgraded to 0.9.29
    * Firewall rewrite, fully modular netfilter/iptables support
        - Syntax of /etc/config/firewall converted to UCI
    * ipkg package manager replaced with opkg
        - package lists moved to ramdisk, lists are not retained between reboots.
        - `opkg update' must be run after each reboot before new packages are installed
    * Broadcom 47xx running reliably with the new Kernel, including b43 wireless driver
        - WEP, WDS and multi-SSID not yet supported
    - AP mode and STA mode are supported with WPA, WPA2, or no encryption
    * IMQ and Traffic shaping fixed with newer kernels (2.6.25+)
    * Sysupgrade for x86, broadcom and adm5120
    * New web interface (LuCI, Lua Configuration Interface)
    * New HAL and driver for Atheros based WiFi cards
    * Attention towards the integration of security updates
    * Build system cleanup
    * Package maintaining and updates between releases
  

So I've been thinking about what services I need to put up on my node(s).
You know there is the now old saying, "Content is King", there are references
on wikipedia, that describes what this means. In a nutshell its, people come back
to you web site if there is interesting or relevant content.
There is also the community factor to, maybe its not just the content but the
community that contributes the content.

Anyhow, so I've been scribbling down ideas for services to put up on the
server attached to the node. Obviously a web server, Jabber, VoIP ... erm ...

What else do folks use on their nodes and use from other peoples nodes?

Has anyone opened up their EeePC and connected a pigtail to its MiniPCIe wifi card for stumbling? Looking at some internal EeePC pics online it should be quite trivial to do (even if it does void your warranty). It's mentioned online that it uses u.fl connectors on the board, I assume a pigtail for this could be made quite easily with RP-SMA on the other end, does anyone have any thoughts about this?

Some pics online of the 701's 802.11G card (not my pics, just some i found):

We're looking at some performance improvements and some new features. Should be packaged up for platforms of interest shortly.

hi all,

Top of tree has been tagged to OLSRD_0_5_6_RC1.

source tarballs can be downloaded at:

i am asking now the package maintainers to download, compile and test
on their target system and provide feedback (both positive and negative
feedback is welcome).

tentative release target for 0.5.6 will be May 10th.

Some months ago I purchased a GPS mouse from the map shop. The device is a; G-Mouse GPS, Model GGM309. Its USB, has a 1.5m cable and has a magnetic base. Cost me about $140. You can get them a little cheaper on ebay, but I couldn't wait ;)

So, I've been driving around, with the laptop and gps in the car, mapping out various roads on my commutes and side trips =). Many of those trails have been uploaded to the Open Street Map site. I also joined the Australian OSM talk mail list. It has been very useful as there are a bunch of local folks that have offered lots of advice on specific problems that I experiencing. The main one was the tools was the gpsdrive to gpx conversion tool. With this new gpsdrive2gpx.pl tool, I can convert the gps trails easily. Lots more fun to be had =)

So the setup is pretty simple, the gps plugs into the USB on the laptop, GPSd talks directly to the gps and all the clients connect to GPSd. I fire up gpsdrive, wait for the gps data to sync as the satellites coverage to settle. From there I drive to my destination and save the gps trail. When I land on a network, I convert the file to .gpx format and then upload to OpenStreetMap. Wait for the .gpx filed to be verfied then fire up the online editor and trace out the gps trail and name the streets and roads. Some time later the streets are rendered and shown on the public map.Easy.

I just dragged out an old Foxtel dish and looking at it, it would appear that it is originally set-up for horizontal polarisation as its higher than it is wide?

I just tried a USB WiFi adaptor at the original focal point but not having much success yet, would that be about the spot?

Routerboard 100 series comparison, from left to right:

The 3 Amp regulator has an approximate 2V overhead required to achieve the desired voltage eg: 14V for a 12V output or 7V for a 5V output.

So we only need to calculate the resistance of the Ethernet run to determine the minimum injection voltage.

Cat5e I believe is 9 ohms per 100metres, so a 10 metre run would be about 0.9 ohm.

At 2 amps (a typical current draw) The expected drop would be calculated as:

V = I x R so this would be 2 x 0.9 = 1.8 volts.

So the minimum ejected voltage required on a ten metre run at 2 amps would be:

1.8v + 2v + 12v = 15.8 volts.
